Scientifically proven to be effective, slow release and with less side effects.
2. Koji Zinc
Koji biomass contains 6-8% zinc on a dry basis, fine powder for easy formulation with other ingredients, less than 200 mg provides 100% DV on zinc.
3. Koji Selenium
Koji selenium is highly concentrated and provides 100% DV in ultra small dose.
4. Koji Chromium
Koji chromium is highly concentrated and provides 100% DV in ultra small dose.
